Don’t bother. Bluetooth is garbage.
Don’t bother wasting your money. Have to keep doing a factory reset to get it to play music after turning it back on when it’s been off. After a factory reset it will stay connected to the phone and play music. If you turn it off and then back on later, it shows connected to the phone and playing the music, but there’s no music actually playing. You have to reset the unit, then it will play again. Beyond annoying. Just spend the money on a normal name brand and save yourself the aggravation. ... show more

Song Album Does Not Display on Screen
Misleading color display, maybe it has something to do with Spotify however it does not display the album image on the screen. I've tried dozens of songs and it will only display a blank album photo.

Sounds great for the price, remote unit doesn’t work properly
Sounds good, great product for the price point. The remote doesn’t work like it’s supposed to though, not sure if it’s an issue with the cord, or something else. Still messing with it hoping to figure the issue out before I decide whether or not to send it back. The main unit works great and it sounds better than the kicker that came on my boat, and has a lot more eq settings to utilize. ... show more
